Description
Technical field
The present invention relates to sponge and goods thereof, be specifically related to photo-catalytic antibiotic sponge and pillow thereof, mat product.
Background technology
Pillow, mattress, cushion are the articles for daily use that people want intimate contact every day, and whether its clean-up performance carries disease germs very big to the human beings'health influence.The Britain scientist delivers the research article on " science " magazine, report finds in each gram pillow material several thousand fungal spores are just arranged, contain the fungal spore more than 1,000,000 in average every pillow, wherein common aspergillus tubigensis is most possibly diseases induced, as the cross infection that causes catching a cold, aspergillus tubigensis pneumonia, sinusitis, asthma deterioration etc., pillow, mattress are called as invisible, easy uncared-for killer.
At present very limited to the sterilizing method of pillow, mattress, medical experts' advice still is often to be placed under the sun to be exposed to the sun, and preferably one or two months clean once, change a pillow one or two years.These traditional methods are taken stopgap measures and can not be effected a permanent cure, and can only kill the part bacterium for the moment, can not keep sterilization effect muchly, bothersome effort.And often change pillow, mattress and concerning a lot of people, hold economically and can't stand, not to be worth the way advocated.Also the someone proposes in indoor set ultraviolet ray or ozone sterilization device pillow, mattress to be carried out sterilization, the shortcoming of this method is that sterilization does not have selectivity, persistence, indoor iron furniture, electrical equipment etc. are had corrosive nature, and this equipment price is higher, is unfavorable for promoting.
Recent years, also the research invention of some sterilization pillow, pad proposed, the first is done core with flexible materials such as silk floss, acrylic fibers silk floss, eider downs, carry out High Temperature Sterilization earlier, carry out drug treating again, as a kind of antibacterial health-care pillow, pillowcase and pillow lining are the antibiotic cloth of handling through anti-bacteium deodorization finishing agent, pillow constitutes by three layers, be respectively the Chinese medicinal plant layer, eider down workprint layer and negative-ion fiber layer, integrate antibacterial, antibiotic, clear away heart-fire make eye bright, produce refreshing effect to the mind, the sterilization taste removal, plurality of health care functions purifies air; Also have with the sponge is pillow, in sponge, add additive, earlier the medicine of intending adding is made powder or liquid, former with sponge again, batch mixes, fully stir, put into designed forming mould then, by normal foam process foaming, this kind medicinal sponge be look add the difference of medicine and make the bath sponge with sterilization or the cushion of medical care effect, mattresses etc. also can be used as pharmaceutical carrier, this based article plays certain sterilization and health-care effect, the comfortableness that also can keep the pillow mattress, but germicidal action can not be lasting, along with distributing of medicine, or because of washing causes drug wastage, the very fast disappearance of germicidal action; Another kind of is partly or entirely to be packing material with Buckwheat shell, Semen Crataegi, bamboo carbon, herbal medicine etc. after germicidal treatment, as a kind of production method of medicine-filled pillow is that the work in-process of space wadding and kongpo monkshood root, Folium Eucommiae, Japanese Honeysuckle are made the filler of pillow, make through sterilization, sterilization, the general comfortableness of this based article is poor, and peculiar smell is arranged.
The bactericidal disinfectant material of synthetic can be divided into inorganic and organic two big classes, because a little less than organic class anti-biotic material exists germ resistance, thermotolerance, less stable, self degradation production and volatile matter may be harmful, be not suitable for shortcomings such as high temperature process, limited its use; Traditional mineral-type antiseptic-germicide is supported in carriers such as zeolite, zirconium phosphate, flux, silica gel, gacs by metal ions such as silver, copper, zinc to be formed; Sterilizing agent has ozone, Peracetic Acid, hypochlorite, stablizes dichlorine monoxide etc.In recent years, be that the sterilization and disinfection effect of the photocatalyst material of representative has obtained extensive studies with the nano titanium oxide.
TiO
2Band gap between valence band and empty conduction band is 3.2eV, and under the illumination condition greater than the 3.2eV energy, electronics can produce corresponding hole in valence band simultaneously from the valence to the conduction band, and the hole easily and the H of surface adsorption
2O or OH
-Reaction forms the activity hydroxy with strong oxidizing property, electronics then with the oxygen molecule reaction of surface adsorption, generate superoxide ion (O
2 -), superoxide ion can further react with water, generates perhydroxyl radical (OOH) and hydrogen peroxide (H
2O
2), activity hydroxy, superoxide ion, perhydroxyl radical and hydrogen peroxide all can react with biomacromolecule such as lipid, protein, enzyme and nucleic acid molecule, directly infringement or the biomass cells structure is caused damaging widely destruction by a series of oxidation chain reaction, can also or resolve into innoxious substance with the degraded of obnoxious flavoures such as airborne formaldehyde, benzene, toluene simultaneously, reach the purpose that purifies air.
Nano-TiO
2Photochemical catalysis has following characteristics: (1) is antibiotic rapid with sterilization effect, sterilizing power is strong, the reactive behavior that activity hydroxy is very high, can divide the organism that is deconstructed into bacterium quickly and effectively, add the synergy of other reactive oxygen species, therefore, compare with the silver-colored loaded mineral-type anti-biotic material that has strong antimicrobial effect equally, its action effect is more rapid; (2) have antibiotic and bactericidal effect, TiO simultaneously
2The activity hydroxy that produces by photochemical catalysis can decomposing bacteria growth and breeding need organic nutrient substance, suppress that bacterium strengthens and growth, thereby reduced bacterial number to a great extent, reach antibiotic and germ-resistant purpose; (3) property killed completely, the inorganic fungicide that metal ions such as silver, copper, zinc support can make cell lose activity, but after bacterium is killed, can discharge pyrogenicity and deleterious component such as intracellular toxin, intracellular toxin can cause diseases such as typhoid fever, cholera, and photocatalysis can not only slacken the vitality of bacterium, and the okioplast of energy attack bacteria, permeates cell membranes is destroyed the internal structure of bacterium, thus kill bacteria completely; (4) has the mildew-resistant effect; (5) the wide and good stability of suitability, TiO
2Safe and harmless to the people, be used widely TiO as makeup, toothpaste filler, whitewash etc.
2The anti-biotic material action effect is lasting, utilizes the UV-light that contains in sunlight, the luminescent lamp to make excitaton source and just can have antimicrobial effect.
1985, the Tadashi Matsunaga of Japan etc. at first found TiO
2Under UV-irradiation, germicidal action is arranged.The experimental result report is with load TiO
2The newborn bar acidophilic bacteria of particle co-cultivation, yeast, intestinal bacteria can thoroughly be killed under the metal halide light irradiation.With TiO
2Be fixed on the continuous sterilizing experimental study that flows on the cellulose acetate membrane, obtained good effect equally.A large amount of studies show that TiO
2Nanometer film has killing action to bacterium, virus, tumour cell.
